10.2.6. PORT E / Odometer input
The PORT E is an alternative port that can also be used as an odometer input for some applications. It can only be
accessed directly at the TTL level, through the DIL connector X15.
The connector has the following pinout:
Pin # Definition (at TTL side)
1
PORT E TX (Not implemented)
2
PORT E RX / ODO A
3
SYNC IN E / ODO B
5
GND
Note that the ODO A signal and SYNC IN E/ODO B have a reverse polarity while the PORT E RX will behave as a
regular TTL UART port.
10.2.7. CAN
CAN bus operation is available by default on the dedicated DB-9 plug (X2) using a standard CAN pin-out as
follows:
Pin # Definition
1
NC
2
CAN_L
3
GND
4-6
GND
7
CAN_H
8-9
NC
A CAN bus termination resistor can be implemented by moving the X1 jumper as follows:
X1 jumper
position
Meaning
1-2
120 Ohm Termination OFF
3-4
120 Ohm Termination ON
Alternatively, putting off the X4 jumpers will give access to the direct TTL CAN interface signals.
The pinout at X4 level is the following:
Pin # Definition
1
CAN TX
2
CAN RX
3
GND
4
GND
38/48
